I have a few things on my mind this week. We have to talk about Japan and the BOJ. Last week’s decision by the BOJ to raise its deposit rate above zero for the first time in 17 years cements Japan and its central bank as a counter cyclical indicator, of sorts. While major central banks have spent the majority of the past 18 months raising interest rates, the BOJ has stubbornly resisted calls to exit NIRP, despite rising inflation. Now that the ECB, BOE and Fed are on the cusp of lowering interest rates, the BOJ is pulling the trigger on a hike. The BOJ’s decision raises a number of fundamental questions for global macro traders and thinkers. The most obvious one is whether the twin inflation shock from Covid and shifting geopolitics is now pulling major developed rate markets out of their ZIRP/NIRP funk. And if they are, does this mean that the idea of long-term gravity of rapidly ageing population weighing on inflation and interest rates is wrong? Is Japanification now reversing? I am sceptical, but if Japan manages to escape, it would go a long way to falsify the idea of a determinist link between ageing and disinflation.

I really enjoyed @EconTalker's conversation with @tylercowen, the founder of the most widely read economics blog out there, reminding us that there is still value in reading the grand old masters of economics. I enjoyed re-reading most of Keynes’ the General Theory for my essay on fiscal policy, and it was also fun to remind myself about Milton Friedman’s permanent-income-hypothesis for the essay on the life cycle hypothesis. But in reality, I fall foul of Tyler’s accusation of an economist who is probably not as well acquainted with the classics as I should be. I have read very little of Smith for example, I find Hayek very difficult to read, and as an economist interested in demographics, I also regret to say that I have only read few parts of Malthus in the primary versions. Fortunately for me and others, Tyler has made his new his new book—"GOAT" of economics—freely available, and I am looking forward to dig in over Christmas.
Read MoreJapan invariably looms as the central case study for the economic and societal effects of rapid fertility decline, population decline and ageing. Japan is, measured by median age, the oldest country on earth, excluding the greying millionaires of Monaco and the some-5,000 people on British St. Helena. At the end of 2021, Japan had a median age of 48.4, well ahead of the second major country on the list, Italy, with a median age of 46.8. Japan is about to get older still. According to preliminary estimates, the country’s fertility rate fell further last year, albeit marginally, while the gap between births and deaths remained wide as ever. The number of live births fell by 5.0%, to 770.774, while deaths rose by 9.0%, to 1.57 million. Japan’s rapidly ageing population is the result of a quicker and more sustained post-1945 fertility transition than in other developed economies.
Read MoreTo the extent that birth postponement is a key feature of the second demographic transition, South Korea is a poster child for the phenomenon. Recently, we learned that South Korea's total fertility rate fell to an astonishing 0.78 in 2022, from 0.81 in 2021, the lowest period fertility rate on the planet. The first two charts paint a clear picture. The first shows the sustained decline in fertility rates, which began in the 1960s. In 1960, South Korean women were having about six children per women, a number which had declined to just over four by 1970 and just over two by 1980. By the middle of the 1980s, fertility fell below the replacement level, and the decline has continued since, despite temporary rebounds at the start of the 1990s and again at the beginning of the 2000s. Period fertility resumed its decline around 2015, and the result to date is that South Korea has the lowest recorded total fertility rate on earth. The second chart plots crude birth rate across age and 20-year time periods, which is a good way to distinguish between quantum and tempo effects.
